Ok, I tried to figure out what the annual savings would be, if any, among the different 3 series options for 2009. Feel free to comment on the numbers. The fuel prices are from MarylandFuelPrices.com, using my home city. I also estimated 15,000 highway miles a year for driving (as it would be easier for me to calculate that way; I understand that is not necessarily representative of everyone's individual commute). The 0-60 times are based on BMWUSA.com, plus the 6.2 seconds for 0-62 noted on the first page of this thread.

So, total savings (under the facts assumed here) for the 335d is $40.75, compared to the 328i, and $218.36, compared to the 335i. That surprised me, as I had been a big proponent of the 335d, even if it is coming in automatic-only guise. But now with diesel prices at 68¢ per gallon more than premium, the annual fuel cost differential is pretty small. That's a change since the last time I tried this analysis (http://www.e90post.com/forums/showpo...&postcount=171).

My 328i gets 33 mpg highway. I bet the 335d will also get more than 33 mph highway though.

And the fuel savings are sort of negated by the 335d's higher price vs the 328i/335i. At least for a couple of years.
